Answer and Explanation:
The computation of the percentage of change is as follows;
a. For 2020 to 2021
= (Net income in 2021 - net income is 2020) ÷ (net income in 2020)
= ($473,000 - $503,000) ÷ ($503,000)
= -5.96% decrease
b .For 2021 to 2022
= (Net income in 2022 - net income is 2021) ÷ (net income in 2021)

= 10.15% increase
In this way it is calculated
